I'd say if you purchased a Mac Pro, it's still the same. If you find yourself not having enough power, you bought the wrong machine to begin with (probably modern threadripper pro would be what you should have been looking for)
If the computer satisfies all your performance needs, what use is it to "feel frustruated" over something that was expected to come?
Don't feel Fear of Missing Out. The Mac Pro didn't change. Your feelings about it changed because of marketing and advertising (ie apple trying to persuade you that you need the M1, when in fact your computing needs are being taken care of already)
Wait for the next generation after that current M1/M1x mac pros and go for the next generations when apple comes out with 128 Cores and 256G of ram.
One constant of computer industry, there will always be the next chip, the next computer, and by then, the fancy M1 Mac Pro will become obsolete. Exactly like how nobody wants a 486 computer anymore but when it was released it was the hottest thing on the planet. Its day will come when everyone says "oh that M1? that was a slow POS that is now ewaste"
