The one and only time I removed my SAI valve was when it & the entire system made a graceful arc through the air, en route my trash can. (Only partially true as I sold the SAI pump on Ebay.)

That said, I like your solution to remove the thing.
... with the hole saw chips in and around the SAI system?
Didn't seem to be an issue as the valve internals seem to block the hole, now having done the removal a while ago I have not experienced any problems.
Seems there are more elegant and less labor/time intensive solutions, documented to removing the SAI check valve.
I agree if they work.
In my case, I tried the crows foot wrench approach and saw the casting under the valve seeming to flex. I was concerned about cracking it and turning the job into something bigger. I also tried to grab the valve body and turn it but it just would distort, no joy. In my case, the valve had not been serviced for a long time, if at all, so it was really frozen in place. This led me to the aggressive approach I took as a last resort. Seems it may not be the first way to try getting it loose but is certainly the last.
Wanted to add some notes to this thread.
When removing the check valve sometimes the pulse impact of an air wrench will break a thread loose without damage where the more constant force applied by a hand wrench won't work or will distort the part involved. Also, an experienced mechanic suggested to me that sometimes using an impact wrench in the tightening direction before attempting to remove a threaded part can break its seized threads loose allowing for removal. Who would think?
I purchase a 1/2" drive air impact wrench at LIDL for $28. Harbor Freight has inexpensive ones as well.

Be very careful using impact tools on that valve, the aluminum distribution body it screwed into can crack and break off. We had one happen here, if you think the valve is a bear, replacing that body is way way worse.
