There’s a recent change that threw away the powers I enjoyed. These powers removed the need for me to retype passwd for sudo access in a different bash session, if it hasn’t expired.

This is guarded by the tty_tickets setting, see man 5 sudoers about it:
tty_tickets If set, users must authenticate on a
per-tty basis. With this flag
enabled, sudo will use a file named
for the tty the user is logged in on
in the user's time stamp directory.
If disabled, the time stamp of the
directory is used instead. This
flag is on by default.
So you might want to disable it. This is done by setting it in the Defaults, with a line like
Defaults !tty_tickets. Notice that several default switches are to be meant comma seperated.
