Not that it's an unimportant issue, mind - I'd think that ideally most
such services (local ones at least, not express coach services) should
accept TfL tickets for journeys wholly within Greater London.

Which would require them to install Oyster card readers and
particicipate in the ODTC revenue sharing system. Plus would they be
paid nothing for an Oyster card that had reached its daily cap or a
child photocard ?

Abellio Surrey (services like Guildford-Kingston) have a "Oyster Match"
fare for the segment of route within Zones (and a bit more). You pay in
cash but at the Oyster flat fare rate of 1.40, for eg Kingston to
Dittons Winters Bridge or to Hampton Court.

Metrobus have introduced what I think is the first TfL bordering smart
card for bus travel

It uses the standard GoAhead branding "the key".

It only holds day and weekly passes at present.

Just worth noting, lest there be any confusion, that Metrobus (Go-Ahead) is
a quite distinct company to Metroline (ComfortDelgro) - the latter being the
operator of the route 84 service mentioned by the OP, whilst the former
(Metrobus) having their territory in Surrey and Sussex along with a number
of TfL tendered routes in south London.

(Not suggesting for a moment that Mr Dickinson was muddled by this though!)
