Does it matter if Boris did say ‘let the bodies pile high’?

Like almost everyone else writing on the subject, I have no idea whether Boris Johnson told colleagues in October that he would rather ‘let the bodies pile high in their thousands’ than have another lockdown. When such words are reported, they are given to journalists ‘on lobby terms’ and are therefore unattributable. But surely the report should indicate from which point of view they come. In this case, the BBC cites ‘sources familiar with the conversation’, a phrase which gives it permission, it thinks, to run headlines like ‘Boris Johnson’s “bodies pile high” comments prompt criticism’, as if it knows that the Prime Minister definitely spoke those words. Surely licence-fee payers need also to be told that the sources giving these stories are Boris’s enemies, just as clearly as those denying them are ‘Downing Street sources’. This is a war, so war correspondents should explain with whose troops they are embedded.
