That sounds like a good idea to me.

I looked up some statistics that I compiled a few years ago when the
predominant macro package for our documents was AMS-TeX (more than 95%).
The sample size (328 documents) was I think too small for the results to
be as useful as one might hope---for example, \Hat was indeed the most
commonly used double-accent macro but it only occurred in one of the
documents (30 instances in that document). By comparison \widehat and
\hat occurred in 71 and 63 documents, with similar stats for \widetilde
and \tilde. In compiling the stats, however, deprecated usage like
\hat{\hat{...}} would not have been caught, since the filter only
counted control sequences, not combinations.

I could mail you the stats file separately, if you want to see it anyway
in spite of its old age, small sample size, etc. It's about 600 lines so
I hesitate to post it to the whole list.

I have an unfinished symfreq' package that counts symbol usage and
writes symbol stats to a file when you run LaTeX on a document; it is
layered on top of the flexisym package that comes with breqn, since that
provides the necessary hooks to attach arbitrary operations to math
symbols. Let me see if I can find some time in the next few weeks to get
that working better and make it available.
