SDK does that for you. You need the ISRs in RAM. This can waste memory. However if you need that kind of RAM use a different hardware configuration.
I wish they had a more proper notion of clocking in the RP2040. It does not cause a problem, but for some people this is really hard. If you get then you just don't care.
Once you go past 25-50MHz the cost of the devices goes up. Therefore most of the gains are in DSP or compute performance not IO. These controllers will become much more like processors. This can be hard to work with for some people. However many just don't care and its usually interesting.
