Standardising editable mode installs (runtime layout - not hooks!)

[sbidoul (Stéphane Bidoul)]

Quoting myself from the other thread:

@sbidoul

I have a use case where, for reasons, the source layout cannot match the installed layout. Typically in the source I have src/myplugin , and in target I want it to be installed in a specific namespace package, such as mytool/plugins/myplugin . A custom build backend can do that at build time, and it would be nice to have such capability for editable installs too.

I can do that trivially with a symlink. Is that feasible with such kind of bootstrap code?
