nix develop takes ages on big directories (alien.top)

I've been seeing that nix develop takes a very long time on large projects, and I believe it's due to the whole folder being copied to the store.

nix-shell doesn't have this problem, but I need flakes specifically because they allow to have runtime libraries, which shell doesn't seem to support. (Translating flake.nix to a shell.nix exactly has different execution results.)

What can I do? I've tried putting the flake.nix on an empty subfolder, and it solves it, but it's extremely tedious and clunky.

Not a solution, but they're working on not requiring flakes to copy the whole source directory to the store.
