  Probably no one has felt a need, simply because the current text file format
  isn't a performance bottleneck in most cases.

The BSDs since (I think) Berkeley Networking Release 2 have used a db format
to supplement for /etc/passwd and /etc/master.passwd for quicker lookups.
Changes to /etc/master.passwd result in creation of /etc/passwd,
/etc/pwd.db, and /etc/spwd.db.  Programs that read /etc/passwd line-by-line
continue to work, while getpwuid() and the like are shunted to the db.

Quite a few sites -- especially mailhosts with large userbases -- rely on
the database files for speedups.  There are even tools that add/remove
records by munging the db files in-place instead of rebuilding from scratch.
