I suspect most people will understand the nuisance of that claim. To be honest, I don't find it all that different then comparing stats from the 1920's to stats from the 2020's.
- Ruth played in stadiums that didn't have outfield fences and in some cases, the outfield fences were held by spectators, who would MOVE THE FENCE depending on which team/player was up.
- The accuracy of stats kept from like 1880 to say 1950 v. today is always in question.
- # of games played changed.
- Level and amount of competition changed dramatically.
- The mound heights changed throughout the years.
- Distance between bags just changed, no takeout slides, disengagement changes, ghost runners, etc.
The reality is the goalposts have and continue to move all the time, which should be expected for a sport that's been around for 150+ years. Comparing stats always needs to be done with some knowledge of the game and a grain of salt. I don't think this is much different.
