Why not?  How many users have aliases?

How does that differ from sym-links?  That the data is in a file of some
sort instead of a file directory can be important, but it is superfical.

I can't think of a reason to object to having dccm check ${dcc_user}
before checking $i, except that I'm not sure it would work.
The value of ${dcc_user} must be valid when sendmail tells the
milter interface to tell the "vendor filter" to process an envelope
Rcpt_To value.  Does Local_check_rcpt get delayed by "delay_checks"?

P.S. ${dcc_whatever} must be used to minimize "name space pollution."
  It's reasonable to hope that ${dcc_whatever} is not used in many
  sendmail.cf files, but I wouldn't bet my life that ${alias_user} is free
