Sure, but in analyzing a password for acceptable entropy, one should be smart enough to dilineate between:

LLLLLLLLLL

and

8x~3uLLx&#@_o

But most people who write password analysis are doing some really quick and dirty checks like [name/email not in password], [password exceeds X chars], [password contains at least 1 of these chars], etc. If you're going to introduce some other check, it should have the nuance to provide some allowances. I've had my auto-generated, 20-char digit/char/symbol PW from keepass get rejected for such things.
