Comment:

 Closing this out since there is nothing wrong with our NaN handling and
 the wkb handling was a decision we made a while ago.

 FWIW, I checked on MariaDB

 and it can't handle NaNs or POINT EMPTY and just returns NULLS for both of
 those

 But interestingly for this
 {{{
 SELECT
 ST_AsText(st_pointfromwkb(0x0101000000000000000000F8FF000000000000F8FF))
 }}}

 It returns POINT(0 0)
