Does a microwave oven inside cabinets need the 'trim kit'?

We're having cabinets built and the cabinet maker needs the size to make the space for the microwave (it is going in a lower cabinet).
He suggested getting the "trim kit" so it looks built in.
So I went to Lowes to look at getting a new microwave, something smallish (we dont use it often and dont want to waste space with it).

But the trim kit makes the space HUGE. The guy at Lowes said you have to have it for ventilation.
But - my last house had a standard microwave in a cabinet, no trim kit. Jus thad a board around it of the same cabinet material to make it look built in.

Any opinions on if you need this trim kit?
This is not for over the stove. It is a counter top microwave, but not sit on the counter. There will be kind of a shelf for it the lower cabinets (so it isn't so visible).
The "trim kit" makes it look built in (rather than sitting on a shelf), and also helps with ventilation. The counter top models aren't meant to be enclosed.

No, you don't need a trim kit. I am confused a bit. Are you referring to over-the-range microwave/hood combo? That would be the only reason you would need it for ventilation. You always need a hood over your range.
