If you could make any changes to D, what would they look like?

Genuine question: is it really so difficult to write such code 
"by hand"? I understand that language servers are convenient, but 
I find it almost impossible to imagine being completely unwilling 
or unable to write code without one.

I ask because I suspect most D users (including core 
contributors) regard this sort of tooling support as "nice to 
have," but not "essential", and therefore do not give a high 
priority to improving it. If it really is "essential" to a 
significant fraction of programmers, we might want to rethink 
that stance.
