Off-topic, but I've noticed recently that this use of "mull", which has
always struck me as distinctively American headlinese, has turned up more
and more in UK publications this year. I wonder why now, rather than at
any time during the last decade or so?

It has been around for longer than the last decade, usually in the
form "mulled over". According to the SED you can blame the 'Merks -
"colloq. US 1879", maybe derived from the action of reducing something
to small pieces etc. [for the purpose of examination] ("mull" being
not 'Merkan but ultimately Teutonic via Old and Middle English).
