It depends on the game and community; but generally speaking, console mods don't delegitimize a run if they don't change the behavior of the game in an illegitimate way. It's common for top-level runners to play on consoles with modded video encoding hardware for better picture quality, for example. When it comes to TAS specifically, most SNES TASes cannot be replayed on console at all because the hardware is too nondeterministic -- the same exact input will not give you the same behavior. It's usually something trivial like an extra frame spent waiting for a sound effect, but that can cause you to (for example) enter the next room with different RNG state, causing enemies to behave completely differently, etc. So being able to console-verify a TAS on a modded console, with a clearly-defined hardware mod that picks a single deterministic behavior from the set of observed behaviors on unmodded hardware, would be a strict improvement over the current status quo of only being able to replay these TASes in emulators.
