I have said it before, and I'll say it again.

Bathroom electrics will one day need supplementary bonding fitting again.

RCDs are not good enough.

It has to be said that something that relies on a passive length of wire
and some pipe clamps is likely to be more reliable than something that
needs working electro mechanics.

I'm struggling to imagine how it could do any harm to have more
bonding than required, as long as it's sound (i.e., not connected to
anything "bad").

Depends on your definition of more than required... if you mean
including bonding in a bathroom which meets the 17th edition exception
and hence could in theory do without, then yup no harm, and not expensive.

However some places take it to the extreme and festoon every bit of
pipework with bonding cables in places where there is not an elevated
shock injury risk. In those cases, there are probably other things you
could do with an installation to get a better return on the investment.
