It depends on the project. If you are making a code editor / ice then yes. Your project may not support working with assembly files. Sure, they are just plaintext (I think? Or are they binary? I think I might be confusing assembler source files and complied files which are machine code), but you get no tooling like autocomplete, go to definition, etc
