Let's separate "supported" vs "unsupported", in the context of WHS, from "released" code and "unreleased" code:
"Supported" for WHS means they've gone to some degree of design and test effort to make something work in most cases and to be reasonably sure it actually does.
It may or may not actually work. If you find a high impact problem that few others have found,
they will not provide any method for you to tell them directly about it--since WHS has no end user support channel--and
won't fix it unless they replace the code the bug is in with newer code. If you find a high impact problem that lots of others find and you all collectively somehow bring it to their attention,
they may or may not fix it now or in some future release.
"Unsupported" for WHS means they have no clue if it works or not and probably haven't spent any effort directly aimed to assure it does.
It may or may not actually work. No matter how many people find a high impact problem and somehow bring it to their attention,
they probably won't fix it now or in some future release unless by accidental side effect of working on related code.
"Released" means that they've gone to a lot of effort to reduce the number of high impact/high probability of occurence problems to a level they consider acceptable. If you encounter one of the remaining high impact problems,
see above re. support. You will have to bear 100% of the impact at your own risk. It also means any function and feature in the code is relatively unlikely to disappear in a maintenance release, but beyond that all bets are off.
"Unreleased" means it still has a potentially very large number of high impact/high probability of occurence problems, many of which nobody has even had a chance to run across yet. If you encounter one of these high impact defects,
see "unsupported" above re. support, but note that they may be slightly more receptive to actually hearing about your problem.
You will have to bear 100% of the impact at your own risk. It also means any function and feature in the code, including it working correctly, may disappear at any time.
