The one sentence you need in following that link is:

"No, but there are U+2A7F ⩿ and U+2A80 ⪀ with slanted equals which might
suffice. "

The principle seems to be that Unicode separately encodes slanted from
non-slanted less-than-or-equal (and similar symbols), but has not done
so for the ones with dot.

The question would be whether the reason for making the distinction for
the non-dotted code points also holds for the dotted ones. If it does,
this might be an omission, if not, as Andrew said, the existing forms
might suffice.
