Phil,
I would not worry. It sounds like some passives sales person want to drive folks to more expensive passives. He/She probably increases a commission that way.
0603 will be around for a long time. I can still buy 1/4 watt leaded resistors too! 😊

We were notified many "common" 0603 MLCCs were going to 52 week lead times. The world is going to smaller packaging. Ok, so how do I make 20 kilowatts with 0402 parts? We work in brute force, 1,200 volts at 100 amps, and still use thru hole parts because they can handle the power. I can see it now, we will use fifty 0201 resistors to get the power level we need. Geesh!
It is going to be interesting how we build in a world of smaller parts.
I know, you can't buy a '57 Chevy new anymore. But imagine if you could Cool!

Of course, hence "...suitably limited implementation..." in my post.
I'm thinking of assembly problems: printing, SPI, placement, reflow, AOI etc - even if one could come up with a suitable mixed footprint stencil aperture, would the resulting solder joint meet IPC-A-610 visual inspection acceptability conditions for example.
Then there is the in-service-reliability aspect of the solder joints
