Personally, I think we'll waste more cycles on this than that it will bring
I'm sure there are more urgent matters.
I know the ifdefs are a mess, but we'll have them anyway (if we do not only
want compatibility with MS's latest and greatest).

Are you planning on creating a branch that can still be actively worked on
by/for those that want to maintain the highest level of compatibility with
.NET 1.1?

I'm not sure if anyone is even interested in this. If there is, then I
assume they will even want to create new (bugfix/security fix) releases.

Sure, but you could just make the 1.0 profile opt-in.
And perhaps only run the build bot test for that profile once a week (and
leave it up to contributors to deal with it).

I understand, and making the 1.0 profile opt-in would deal with that.
You should also make it clear that the 1.0 profile is no longer endorsed by

Is this something that you will do or want to do ? ;-)

Note that I'm not opposed to making the 1.0 profile a second-class citizen,
but I consider removing it altogether a radical change.
