I agree. However you do need to be careful with some of the techniques/processing of 24/25p conversion. Some software or hardware will duplicate frames, blend frames, drop frames or interpolate new frames which can have various negative effects on the final image.
Thats why re-interpreting the footage is the best way - it doesn't change any of the individual frames or the sequencing, it basically just changes how the timecode is read. So the 25th frame of a clip gets re-written from 00h 01s 00f (in 24p terms) to 00h 00s 25f (in 25p mode) and so on for the rest of the clip. It just tells the file to play back differently without actually making any changes to it.

I don't think anybody could, as long as the clips are played directly from the source (ie the camera's LCD screen) or a PC or some other hardware which can handle it natively. But not all hardware can handle it natively (because of the differences between PAL/NTSC) Playback 24p on a PAL 50hz TV and it will duplicate/blend frames. Drop it onto a 25p PAL timeline in an NLE and the same thing will happen.
While the difference between 24p and 25p is imperceptible, the way they behave when played on incompatible/non native equipment or software is
very perceptible. So it has to be corrected, which is really no big deal. 30p to 25p... now thats a
real pain in the arse.
