I decided to implement it because:
1) The way the underlying text management data structure is currently
implemented these repetetive changes of the same text regions presents
an (almost) worst case in terms of memory usage.
2) It turned out to be relatively straight forward to do. It might
not support all the special cases of vim. For example it is currently
not repeatable.
Also due to conflicts with existing keybindigs (<C-a> alignment of
multiple cursors) it is currently not enabled by default. You will
need something like:
:map! normal <C-a> <number-increment>
:map! normal <C-x> <number-decrement>
