Why D7 is really still a beta and should never have been released

Because I like seeing what other people are doing, I have joined several D7 sites and found they are all messed up in one particular way.  These sites - including mine,  are missing a basic function that in my opinion makes them seem amateurish, and also corrupts their data. I am talking, of course, about the inability of D7 to have an empty (null) result in a multiple select field made from a pre-defined list. 

It sounds a bit academic, but the lack of this function totally screws up both the join form and the search functions, and goes to the very heart and soul of the software.  Unlike in D6, where this worked fine, on D7 if you use a predefined list on the join form, and set it as a required field, it will select whatever is on top of that list unless the member changes it.   This is such a basic database function, that it is a little shocking that it was never fixed.  Making the join form work properly should have been the highest priority of the development team, but there were major problems with the join for that remained broken throughout all the betas, while emphasis was put on non-critical modules. 

Even worse, it how this flaw affects the search function.  It is impossible to design a search with two fields.   If the user selects one of those fields, and not the other, the second field will be selected anyway, making the search worthless.  On my site I need to have a search that has a list of "industries" and a list of "trade countries" - it is key to what I am doing, and again worked just fine D6.  This is probably important to everyone here but on my site it is almost the very reason for its existence.  Without it, I probably should have just spent a half hour putting together a Ning site, instead of spending a year and a half of my life trying to make Dolphin work properly. 

It is not like this hasn't come up before.  In fact, almost everyone who reaches a certain point in the development of their site realizes this is a major problem.  Here is one thread where members here tried to gain attention to this issue, but there are several others: http://www.boonex.com/unity/forums/topic/Select-default-country-for-all-dropdown.htm#topic/Drop-Down-Menu-Select-It.htm

I tried to communicate with two different Boonex developers about this but they both tried to say that it really wasn't a problem, or that "this is just the way the software works".  Another member here told me he talked to a Boonex developer who said it would be "impossible" to fix.  Clearly, they just want this issue to go away.  A Trac report has been written on this at this linK:  http://www.boonex.com/trac/dolphin/ticket/1627

Note how the developers or someone at Boonex has tried to delete or close this report- and most recently redefined it from a "defect" to an "enhancement".  This is NOT an enhancement - it is a "mission critical flaw".  In my opinion, all work by Boonex developers on "mods" for the marketplace should be immediately stopped until this is fixed.  In fact, all mods already published by developers should be pulled, and a team should be assembled to fix it. 

While Boonex may consider the current D7 to be the "offical release" - many of the rest of us still have to call our sites "beta" because of this defect.  Please Boonex publish a patch or a minor release to fix this serious issue - your software really doesn't work without it.
