It's ironic that in order to accommodate POSIX for one construct IBM
resorted to another convention which implementations "are strongly
encouraged to avoid":
https://pubs.opengroup.org/onlinepubs/9699919799/xrat/V4_xbd_chap04.html#tag_21_04_12
Application developers should avoid generating pathnames that start with
"//".
Implementations are strongly encouraged to avoid using this special
interpretation
since a number of applications currently do not follow this practice and may
inadvertently generate "//...".
