Consistent files in plugin repository

We noticed several times in the past that a file in the plugin repository might change without bumping the version or changing the URL.

This causes some build tools that support digest based caching and validation - to fail when they depend on URLs from the repo.

For instance - 

ERROR:  Error downloading [https://plugins.jetbrains.com/files/7322/88054/python-ce-201.7846.93.zip]: Checksum was 648438d26e85072f90a62f9f5b9f9b983a49f3cb752e87d01f915cb6a03644b9 but wanted a3d7217794619dfa0432d922218dd875f49658939c6e5a54c01f99b333d35e12

Can we do something in order to promise not overwriting the files in the repository (but upload new files to different name/location?)
