I certainly would recommend it, there are ample people on the
mailscanner lists who will go out of their way to help anyone with this
combination, as you very well know, but you are correct in as much as
Wietse and the postfix community doesn't, and those who have  been
around long enough know why (this isn't the place for that discussion
either for those who don't), however there are many large organisations
happily using that combo and that number has grown over the years as
postfix becomes more widespread use over sendmail etc.

Yes, I have setup this milter on memory constrained VPS's for clients
where neither MailScanner or amavisd-new will work without the kernel
killing off stuff for out of memory on the entry class VPS offerings. I
do recommend it.
