pg_multixact_member file limits

Are there any limits on the number of records in the postgresql/12/main/pg_multixact/members directory? We have a database that has grown to tens of thousands of files in this directory during an autovacuum after a large data purge. It shrank after the autovacuum completed.

Wouldn't that be a function of how much filesystem performance degrades as 
the number of files in a directory increases?
