Regardless, the process to drop/replace something is not trivial.  This
project is not like other desktops; we don't just drop or replace things
on a whim.

The process would be:
1.) Develop a procedure to replace twin with kwin4 on users' test systems
2.) Those users would need to thoroughly test the replacement for many
months, noting any regressions and having them fixed upstream.  Upstream's
response time and overall regression rate would also be evaluated at this
time.
3.) If the replacement after testing looks viable then a deployment
procedure would be created.  twin would still be available, but kwin4
would be an option, either in build or in package installation
(preferred).
4.) If the majority of end-users choose kwin4 at this point, then twin
would be deprecated but still maintained as compilable in the TDE source
tree.

As you can see this is not trivial.  These guidelines are be applied to
any integral component of TDE, including the HAL replacement, and are not
meant to be an onerous set of rules to prevent progress.  Rather they are
meant to lessen the possibility of sudden unexpected breakage for corner
case users, as has been seen many times before in open source history.
