The wrong frequency in itself is bad for transformers, then some motors wouldn't run at the correct speed

Edit: the Japanese grid is fantastic in that regard

Tell us more about the Japanese grid, please.

From memory (dating back Fukushima, 2011) they have both standards, the country is cut in half.

It was not even possible to export energy from one side to the other after the tsunami

Neato. Apparently it had to do with when each grid bought its starting supplies. Generators bought from the US were 60hz and Germany were 50.

In the same idea, those geniuses in Texas aren't connected to the national grid to be free from federal regulation.

Add the UK is not synchronous with the continent so the 'NEMO' link has to operate in direct current (bidirectional 1GW or so...)
