I don't think this is the place to debate the politics of free software.
This is an old argument and a lot of people do disagree very strongly with
what you just said, so please let's not go there.
The mail notification doesn't seem necessary to me, though. There are
other clues one can use to detect the popularity of scsh. One is available
by looking at download statistics left in the ftp server logs. Another is
traffic on this mailing list. Another is evidence of scsh applications
being distributed by people on the internet. The last one is the crucial
one; knowing how many people download and build but never actually use
scsh, is probably not that useful a statistic.
