Well, lots of things can be proposed and everyone has different ideas.
I think that what's really needed for WRI is not to get too distracted by various proposals, but *focus* on doing a few things well, and especially focus on fixing bugs.
Primarily silent wrong result bugs.
The two nastiest examples (that affected me) tat I can recall are:
Tally with a custom test was broken in version 6, and gave wrong results silently. It wasn't fixed in minor releases, we had to wait 2 years for 7.
IsomorphicGraphQ was broken in 8 and gave wrong results silently. It also crashed sometimes. The crash was fixed in a minor version, but the silent wrong result (which I consider a much worse bug) was not fixed until v9 two years later.
These silent wrong results are very serious problems because they are completely unexpected and should be fixed as soon as they are discovered.
They are not at all in the same class as an incorrect result for a definite integral with a singularity, which is expected---no CAS will be perfect in this. Such a bug in either Tally or IsomorphicGraphQ is not expected
