Immich has a concept of storage template, which you can use to set the directory layout using year and month and maintain the original filename.

Thanks, I wasn't aware of that. Do you know why it is disabled by default? The docs say "for stability reasons" but don't elaborate further.

Historically there were integrity issues with the storage template, these should now be resolved however. The reason is disabled is quite simply that most users don't need it and it can cause a lot of IO in some scenarios, for example if your upload and library directories are on different mount points.
