In a domestic set up ie average (if there is one) house is there any reason you wouldn't use a RCBO but a MCB and a RCD?
I can't think one

Cost. Also the RCCB will switch the neutral pole whereas the RCBO may well be single pole and leave a neutral/earth fault in situ. Not good if there is an upstream RCD.
Did you mean 'not good if there is not an upstream RCD ' ?
If there is an upstream RCD then that will clear the fault and the SP RCBO will not be so much of a problem.
But the fault will cause potentially a total loss of supply.

RCBOs single and not double pole (majority)
RCBOs expensive compaired to a split dual RCD board fully loaded
RCBOs take too much room up in average domestic boards, not curves though
RCBOs have horrible white fly leads which look like a ball of wall in the boards and make the boards harder to look neat
RCBOs have horrible long neutral leads which look like a ball of wall in the boards and make the boards harder to look neat.
RCBOs are better for individual circuits rather than an RCD covering 5 breakers in a split due to nusience tripping
How many more examples would you like?

A curve board with an s type RCD up front and individual rcbos would be a good choice on a TT system, that said it would cost 150 notes rather than 50 a split would costAre you a fan of RCBO's? lol

A cheap enclosure with a lot of space above the dim rail unlike most domestic boards, that said when the regs change they may disappear from the market fella.I've not heard the term "curve board" before.
Better than it causing a fire of there wasn't the upfront protection
Can you specify the type of RCBO with regards to the number of poles it is switching as that will affect the answer?
