I've always been really bad at counting seconds and I believe that's because the timers in 50hz PAL games taught me a second is 1166.67ms. Fuck this shit, why did they keep gimping PAL games into the 90's when most of our TV's by then supported NTSC signals? Did they have fucking 60's sets in mind?

No, I think PAL TVs supporting all signals only became the norm somewhere around the mid 2000s

They had to make the consoles for everyone's TVs. So yes that included grandma's TV

RF Modulators.

Almost all European TVs of the late 80s onwards supported PAL60 or even NTSC signals, but only over a composite style lead.
When you threw in 525 line timings on RF modulators, you had all sorts of weird shit happening.
No sound, no colour, flickering image, auto-tuning can't find the signal, bandwidth issues with adjacent channels.

It wasn't until using either composite leads or SCART (both of which carry a simple baseband signal) became the primary connection method that you could get away with it.
Technically it could've been done earlier, but you'd be throwing out a lot of existing sets.

the 2000's, too

I find it extreamly surprising that 525 would have any effect on RF. I can't even remotely conceive of any way in which RF would care about vertical timing.

This is wrong, all the early 90s sets I've had supported 60hz. 80s sets were the problem

It would be interesting to see a study on this. If someone has access to a wide array of old TVs it would be interesting to settle this once and for all.

Late 80s and newer tvs started using those one chip generic CRT controller ics which supported both 50 and 60hz.

What people call "RF" is actually a whole broadcast standard, usually different for each region.
In "PAL Regions" this is usually System B on VHF and System G on UHF.
These standards define line timings, where sound should go, all sorts of things.

If you don't adhere to the standard, it's a crapshoot how things react.
Some TVs might derive frequency of X from frequency Y or only decode colour if it is "logical" for the standard.
This isn't an issue for standards compliant broadcasts, because everything is where it should be.

And that is ignoring how the modulator tries to put together a vaguely compliant signal with non-compliant baseband input. These aren't clever devices, they were $20 pieces of crap even in their day.

I don't see how the number of lines in the frame would have any effect on modulation. As you say modulation is very simple, it does not do anything with sync pulses, it just encode and and decodes composite video transparently.
