I have now trialled there and there are versions on alpha


The "emacs-27.0.50" files are built like a release build, while the
"-snapshot" ones are built like a snapshot build.

In terms of the download size, -no-deps drops from 107M to 46M which is
the most extreme drop. The installer version drops by only 10M because
it's lzma compressed. Uncompressed sizes will be proportionately

Happy if people want to give these a trial to see if there is any
functional or otherwise noticable difference between the two. I update
the build scripts on master in a short while if there are no complaints.
