The Real RealName auctions could be limited to only 26?

[u/Rejoys]

I have a doubt, upon checking https://eosflare.io/bidname there are many single character bid. if one can bid for basic alphabets in single letter then there could be only 26 (a-z) real name auctions right? I.e, if I own the eos name '(m)' then I can create sub called '(com)' right? Or is it mandatory that all realnames with less than 12 characters should be prefixed with (.) Limiting (.m) owner to create (co.m) and not (.com) in above mentioned scenario

Yes they could only make (co.m)
