GZDoom/UZDoom is a similar grey area, it is built on the original Doom codebase but they've added so many features that it's practically its own distinct engine now. Those forks can even render arbitrary 3D models, which OG idTech couldn't do until Quake.
But it is the same overall code structure, the same game, etc.
All these oss quake engines, are they quake? Ironwail, quakespasm vkQuake?
Half-Life 2 sure won't play quake maps nor will it play hl1 maps.
Seems to be using a dnsft.cloud.zyxel.com certificate. Is this a home router?
Funnily enough the looks of this HL2 through this engine makes it flow more with HL1 than I could expect; an interesting reverse Half Life: Source / Black Mesa / demake of sorts.

You won't confuse it with modern Half-Life 2, but the original HL2 engine had far worse graphics than the latest version. Makes you realize how much of the difference between HL2 and HL1 is due to different textures and level design.
edit: there is also the fact that map compilers for gold source games have advanced far beyond what they could do back in 1999. The lightmaps and light sources alone can be far more intricate nowadays than what you would get from the official valve ones in 1999.
