In my opinion there is no fork needed. I would appreciate to
see the 5.7 changes in 5.3.

Several (most?) of the forks in libes/gis/, XDRIVER etc. could be
merged from 5.7 into 5.3. But this requires that someone else than
me checks it.
E.g: If 5.3 users prefer the black X-monitor over the white X-monitor
in 5.7, we cannot merge. The same applies to the improved cursor
We'll certainly not replace the improvements in 5.7 with old code

Minimising divergence requires that 5.3 developers look at 5.7.
Unless they aren't willing to do that, the minimization of divergences
will have to wait, unfortunately.
