Sorry that's bordering at nonsense hubris.

To take advantage of the index you need to identify character sequences in the regex.° (And erix even showed that it only works for 3+ characters in PG.)

Now, while it's possible to identify those sequences at the compile phase - at least in Perl using re - one need's to know which ones are

And regexes are Turing complete.

It might be possible with sufficient work involved, but I doubt it's already done.

You are more than welcome to prove me wrong. Even with a test/benchmark in PG.

Claiming that the complexity doesn't matter is really quite a bold statement.
