I think that the main point is that it is _not_ a big selling point for the 
majority of users, whereas things that the language has already promised to do 
are not currently working properly. So, for the vast majority of users, what's 
currently being worked on does not match what the highest priorities are.

It would be one thing to add SIMD support if there weren't major issues which 
are causing problems for the majority of users. It's quite another when there 
_are_ such issues.

That may be true. And maybe SIMD will be taken care of more efficiently this 
way, but it doesn't match what's supposed to be the main priorities right now.
