I just learned that some labs don't do cross processing of slide films because it is "bad for the machine".
I'm curious: Really? Why?
Thanks in advance!

the simple reason is something unfamiliar, better don't do, else someone's head will be on chopping board.
and also, not much profit earning from film processing, no point making such risk.
thirdly, the results are so unpredictable, if the photographer screw up the exposure, most likely he will screw the lab for messing up the processing.
btw, only those labs serve lot of pro photographers are willing to do cross processing, so don't go to neighborhood labs to ask for this service.
btw, the chemical of the labs processing machine can use for processing many rolls of film, the machine will prompt when to add water or chemical replenisher.
so if contamination happens, the lab staff has to discard whole lot of chemical, flush the machine, that cost a lot of money and man hour.
and if the emulsion of the film peel off during the processing, that will be a disaster, they have to dismantle the machine, clean the all the rollers and the chemical tanks.
