What's the overall rule on Hud mods that only change the huds graphics, without adding any extra features to it?

Recently, a character pack known as "Chaotix Characters" was released, with a new version of Espio with a different jump ability.

Is there gonna be a new Character dropdown for this version to separate the runs, or will it simply be a matter of the mod character version dropdown?

As the title of the thread says, The 2.2.11 update to SRB2 now adds the ability to raise the framerate cap.

Its more so the addition of framerate interpolation rather than changing the actual Ticks per second (TPS)

Additionally, a few stages had small layout changes in accordance of larger scale mod characters. Most noticeably, Egg Rock Zone acts 1 and 2 had its vents resized, and a gravity section altered to work on jump based activation. (This means regardless of how tall or short your character is, they will always swap gravity upon jumping.)

Are the rules going for both the main game, and modded character extensions going to change based on this? Will it be allowed, or will runners have to cap the framerate to 35 like in older updates?

Its likely to have been asked before, but...

When submitting a run, i noticed that characters had a "add value" box. Does this mean modded characters? And if so, where are they viewed?
