The Info section on text properties declares
inhibit-point-motion-hooks obsolete.
That same section also declares point-entered and point-left
obsolete and points instead at cursor-sensor as the new goodness.
cursor-sensor in turn has a variable cursor-sensor-inhibit which is
undocumented --- so what is the new replacement for inhibit-point-motion-hooks?

The NOP operation should do it.
inhibit-point-motion-hooks is used to disable the effects of
text-properties like point-entered/left and `intangible' which operate
at a very low level (they affect everything including like goto-char).
The replacements for point-entered/left and `intangible' in
cursor-sensor do not affect low-level operations (they only kick in
between commands), so all uses I've found of inhibit-point-motion-hooks
can be simply dropped once you don't use point-entered/left and
`intangible' any more.
