Skipping the technical merit of the quoted text for the moment -- I find
the fact that you keep calling the present IDE host drivers (that many
developers helped to fix) as "old" ones or "buggy" ones rather degrading
for their (this includes me of course) hard work.

Especially given your complete lack of familiarity with post-2004 changes.

See for yourself, *50* mostly _trivial_ patches during *5* years:
