At the 2015 World Championships Glasgow, word was that the Men’s Code of Points would go from 10 skills to 8 after Rio, to match WAG. The DRAFT 2020 Code had 8 skills, 4 element groups.
Much later the final decision of FIG MTC was to stay with 10 counting skills. I’ve not yet heard the rationale.
An Aussie gymnast, Luke Wiwatowski, who must plan different routines for 8 or 10 skills, weighs in.

I seriously doubt having less skills leads to more ties. Remember vault only has 1 skill (or 2 for finals), so if there argument that less skills leads to more ties such as the four way tie on bars, then we should be seeing 5 or 6 way ties on vault, but of course that doesn’t happen. The FIG are stupid.
