I see what you mean.

Just opened Electrum and the lowest fee rate does seem limited to 1 sat/vB and there is no obvious way to make an offer lower than 1 sat/vB. When I try to manually set a fee below 1 s/vB I get this message-

'This transaction requires a higher fee, or it will not be propagated by your current server. Try to raise your transaction fee, or use a server with a lower relay fee.'

Clearly some wallets have realised less than 1 can be sufficient currently.

Nice problem to have from a users perspective, but still concerning that transaction demand is so low and use as a MoE is in apparent free fall at least on the primary blockchain.
