No the cabinet should sit on the tile not the subfloor. What if the cabinet
would need changed out? Then you would need to redo the floor as well.

Take your argument to its logical conclusion: if you've already got tiled
floor, do you rip out the tile when you install new cabinets?

The top surface of tile is uneven. Setting cabinets ON it leaves you with
a potentially unstable base and gaps under the cabinets (unless you want
to make your toe kicks out of RUBBER)

That's what shims are for. Shims are going to be required even if you place the cabinets directly on the subfloor.

Cabinets are standard sizes. It's not like your next set are going to be
deeper, front to back, than your old ones. You aren't going to move the
walls to squeeze in a cabinet that is 2" wider, etc.

You are the only one to mention different depth cabinets.

Here, homes where folks installed cabinets *on* tile are the "low rent"
variety; the installation looks very amateurish.

The appearance of the finished product is a reflection of the installers' workmanship -- not weather the cabinets were
installed on the subfloor or not.
As much a reflection on the tile installer as the cabinet installer -
and MANY cabinets today have adjustable levelling "feet" to level the
cabinet - and the "kickboard" or "plinth" gets coped to fit the floor
if necessary - or simply ripped to fit, with the small gap at the
bottom caulked.
