Use custom module name in symlink-project, different from DDEV_SITENAME

[donquixote]

I have this situation where the ddev project/site name is different from the desired module name.

Currently the project name is like "something-drupal" whereas the module name should be like "something_banana".
So the symlinks should go to web/modules/custom/something_banana and not web/modules/custom/something_drupal.
What makes this relevant is that the project contains hard-coded paths which assume a directory name.
(Let's not go into detail about how the problems with my setup are a bit silly. It's an existing project.)

A less silly case could be if we want to have 2 instances in 2 separate dirs for the same project.
So one would be something the other would be something-1.
Currently, symlink-project would create web/modules/custom/something in one project dir, and web/modules/custom/something_1 in the other project dir.

Would it make sense to decouple the module dir name from the DDEV_SITENAME env variable?
