This is a result of #63083, which was a (largely) bug fix that made lifetime parameters use hygiene in a comparable way to other things. Nominating for lang but recommendation is "won't fix".

We discussed this in the Sep 05 @rust-lang/lang meeting and decided this is a "bug fix" and hence "won't fix" is the appropriate result. Closing.
