"Multirepo" is the term I see the most

Thanks! I saw 'polyrepo' too, but multirepo sounds more intuitive.

'submodules' too, but which further implies a) git; b) there's a (CD/infrastructure?) repo which collates the pieces.

Surely micro repos would be more fitting (although probably a terrible idea)
