After reading all the above requirements and upgrade scares...
i "feel" Boonex has to change the product delivery strategy...
as of now Boonex releases the whole cms and allows its members/developers to customize whatever they want and hence we have too much of incompatibility issues...

rather Boonex should release Core framework to the developers with constrains and developers build/or support in building the core features and release their mods for the framework and not for the CMS.

also see more the D8 cms has to be released to the public and the webmasters can customize its look and feel without disturbing the core...
and if there is any requirement for the webmasters it is good and safe to pick it up from boonex's dev repository and plug it in.

and thus it will ensure the quality of the mods, compatibility of the mods for super smooth upgrades in future...

to be simple, boonex cant be like Joomla
its better to be like apple

i can survive my members for a year or two without the basic copy/paste rather than buying copy/paste mod from someone asap and start worrying about the next upgrade :)
