I wholeheartedly agree about the complete lack of a push by Intel to get features onto mainstream parts - whether TSX or AVX-512 or even other stuff like vPro which kills adoption due to split estates and lowest common denominator tendencies.
So I have an 8665U in one of my machines - According to Intel ARK it has TSX enabled (not that I have personally noticed or used the feature):

It seems select Core parts of 9th Gen also had them eg:
https://ark.intel.com/content/www/us/en/ark/products/195328/intel-core-i7-9850he-processor-9m-cache-up-to-4-40-ghz.html
For the 10th gen parts I've not managed to find a core model that includes the capability.
11th Gen tiger lake and rocket lake it seems to have disappeared from the Advanced Technologies listing completely:

https://ark.intel.com/content/www/us/en/ark/products/212325/intel-core-i9-11900k-processor-16m-cache-up-to-5-30-ghz.html
Will have to chase up the next time I speak with one of the Intel architects or PMs about the situation of TSX going forwards because outside of very niche situations Intel is largely silent about this while AMD seems to actively be avoiding the area
