I have found the form `global ${'abc'};` useful in the past to work
around the limits on what PHP can parse as variable names, to allow
naming global settings to match how I like to write them in config
files e.g. 'image.upload.retry_attempts'. I would be very surprised if
there was no codebase in existence that didn't use the other forms,
for better or worse.

For changes like this, the conversation almost certainly needs to
start by stating a clear problem something is causing, and then lead
on to why doing a suggested solution is the right thing to do.
Although this might be a small inconsistency in the language, by
itself, I can't see it causing much harm, except maybe for performance
optimisation as trying to analyze what variables are being used in the
code is hard.
cheers
