You might try benchmarking the regexp engine & the fallthrough matches sometime. You may be pleasantly surprised. I do agree with you regarding the trailing match, but, I disagree with your assessment that the regexp engine is a high performance solution that cannot be aided.

I do benchmark my code, including my work on mod_rewrite,
before releasing it publically. Perhaps you should benchmark it
before you presume to tell me how my own software works.
Indeed, simply parsing the extra line in the .htaccess uses more
cycles before it even compiles the regex and starts looking for a match.

The directives are read from .htaccess line by line, which means
that each character is checked to see if it's a newline.
It takes an extra 50 character comparisons just to read the line,
even before it's recognized as a condititon at all.
On the other hand the regex engine must make only 2 comparisons
to see whether the next character is a "w" or a "y".
Indeed once your extra regex is compiled it's on the order of 2,000 times slower.
