No, changing the update-alternatives call is
a) not necessary on /usr-merged systems,
b) will break on these.

There is nothing to do for netcat-traditional here.

This is an unsupported configuration in trixie. Please ensure your
system is in an supported state (i.e., merged).

Note that other package updates will also break similarly or with
other symptoms.

Hi,

This system appears misconfigured - it is a trixie/sid installation,
but not merged-usr, which is not supported and not possible to install
anymore. Please fix the system so that it is configured as supported
and try again. You can find more information on:
