Perhaps. And perhaps, Tramp shall check and apply "-3" if
possible. Since OpenSSH 8.7, there seem to be more restrictions wrt
authentication. Quoting the man page:
--8<---------------cut here---------------start------------->8---
-3 Copies between two remote hosts are transferred through the lo‐
cal host. Without this option the data is copied directly be‐
tween the two remote hosts. Note that, when using the legacy
SCP protocol (the default), this option selects batch mode for
the second host as scp cannot ask for passwords or passphrases
for both hosts. This mode is the default.
--8<---------------cut here---------------end--------------->8---
