ICANN is discussing the problem of Singular VS Plural new gTLDs at the moment and decisions "should be taken" prior round 2 to begin, in regard to this awful option to allow both strings to exist at the same time. The draft of the report can be reviewed here (PDF download). It starts page 115.
Something that I don't understand
This is an extract of the REAL ESTATE new gTLD report (entitled "Singular and Plural new generic Top-Level Domains") from March 2017, which clearly shows that there is a HUGE difference between the number of registered domain names ending in ".loan" (instead of ".com") and the number of domains ending in ".loans", with an "s".
Of course, I have my idea about this surprisingly high difference but I am interested in hearing other explanations.
