I suppose it's doable but not sufficiently a prominent use case to
bother much.

Stick it on the "nice to have when somebody gets round to it" list :-) But it at least should get put on the list ...

I'll get round to writing all this up soon, so the wiki will try and persuade people that resizing arrays is not actually the brightest of ideas.

The trouble is lack of people talking to each other and thinking that they can rely on the "do one job and do it well". Except of course that you can't square a circle ... :-)

But this really is stuff that needs to be on the wiki, and it's stuff the MD and filesystem people don't talk about with each other, I expect :-(

Cheers,
