I wrote this before, but apparently you didn't hear it. Let me repeat:
$foo on the LHS allows metacharacter matching, for example "a.*b" can
match "a foo b". But \1 only allows literal strings. If $1 captured
"a.*b", then \1 will only match the literal string "a.*b", as if the
regex contained "a\.\*b".

I don't see how you can possibly consider this a "tiny difference".
