We did this on our previous remodel and for 2 sinks in our new home, and they all seem fine. The decades-old sink that we took out when doing our remodel was done this way in really cruddy old builder's grade particle board cabinets, and it held up fine. We used drop-in sinks, so I don't know if that makes a difference.

It's quite common to have to cut down the side partitions for a new sink. Just only notch as much as is needed to accept the sink, you should be fine.

It's mostly fine, but the reality is that you will NEVER be able to change the sink out, and yes, it voids the warranty on your cabinets.

I imagine it would void the warranty on just the sink cabinet, right?

I do 32 inch sinks in 33 inch bases everytime I need the extra room for one reason or another.

Doesnt void my cabinet warranty.. I tell the company I want "scooped sides" and they do it for me...
