Don't know whether this is due to a recent change. But let's analyze.

This tells us, that `(file-readable-p
"/scp:dev-dsk-sdsg-1e-cfbb346a.us-east-1.amazon.com:/workplace/sdsg/lpt/src/A9IFSDataScience/back-testing/Contents/Resources/site-lisp/nntp.so")'
has been called. No idea why. Either, a package keeps this file name and
wants to see, whether the file is still readable. Or the file is still
visited in a buffer you aren't aware off. Note, that
`tramp-cleanup-all-connections' doesn't purge such buffers, this is done
by `tramp-cleanup-all-buffers'.

Could you try to rerun your test with "emacs -Q"?

Best regards, Michael.
