There is an argument to be made that Half-Life: Alyx runs on a “modified Quake engine”. At no point was the engine completely rewritten, though it went through several major evolutions and presumably none of Carmack’s original Quake code still survives… probably.
What matters is that Valve made several major overhauls over the years and is well aware of both the strengths and weaknesses of its engine and taylors its games to them. I mean, you couldn’t run Elite Dangerous on Source 2, but nobody asked. Seemingly, nobody at Bethesda corporate asked if CE was capable of multiplayer (hence Fallout 76), and nobody at Bethesda corporate asked if CE was capable of half the shit that Starfield would have to provide for exploration to be compelling in the way that it is in Skyrim.
The reason for that is because, yet again, for the three hundred thousandth fucking time, Bethesda is using, still, a modified creation engine.
