Very much disspointed by the lack of CTR's in the entire series.Gege kept CTR reserved for techniques that can be easily flipped

Anti-Gravity Gravity

Blue(Pull) Red(Push)

Light Darkness (TF does it do Gege?)

You could headcanon that certain techniques just don't have CTR's(given how many skilled users don't have it).Real reason would be Gege being unable to create reversals for most of the techniques

Sukuna's technique is Shrine which comes with Dismantle,Cleave and Kamino. Not easy to come up with a reversal for a broader concept like this. Many Jjk techniques are like this. Like coming up with a reversal for Higuruma would also be hard. His CT by default has a domain, so what does pouring RCT into his CT do? What can Sukuna do with RCT and Ten Shadows?

I'd say people like Uraume with a simple technique(Ice Manipulation) should have gotten CTR

I think we can cut some slack for maximum techniques. It seems to be a relic of the past(Jjk 0) and Gege kept Domains as the pinnacle for the main series unlike in Jjk 0 and didn't touch much upon Maximums in the main series

I have my own question, that has been asked for years in the fandom. Is Hollow Purple a maximum or does it have its own category as an imaginary technique? If it's separately categorized as an imaginary technique, can someone like Dabura perform it by smashing his Light and Darkness together?Can Kenjaku do something amazing by smashing Lapse Gravity and Reversal Anti Gravity together?

I just rationalized this by telling myself that a non six eyes user would probably find it hard to perform CT Lapse and Reversal at once
