As an example the specs on this look adequate for troubleshooting I2C
waveforms.

I find the test equipment available nowadays truly amazing and
especially at that price... However my old stuff from ~30 years ago
still works (some pots and switches could use cleaning) and I wonder
how long these new items will last. Of course if they were to work for
another 20 years I'll not likely be around to complain about it😉

It really is, although some of the older, better scopes had a lower noise floor. I compared the 1970ish HP spectrum analyzer I was considering buying to newer microprocessor ones at over twice the price and saw no difference in sensitivity or noise.
A 5-1/2 digit Fluke 8800A bench multimeter from around 1980 that I bought for $25 still matches a calibrated voltage standard to the last count. Industry dumps equipment (and people) when age makes their reliability questionable.
Later several shoppers and I were discussing the performance of an expensive deep fringe TV antenna a dealer was selling, and I mentioned an RF spectrum analyzer. The dealer couldn't believe that an individual would own one, but we discovered we all did.
