The venerable dput has not kept pace with other tools for many years.
Dput for example never got the command capabilities announced by
ftp-masters in 2012:
https://lists.debian.org/debian-devel-announce/2012/09/msg00008.html?pow_referer=https%3A%2F%2Fhashman.ca%2F

It is cumbersome for new developers to read dput's documentation and
learn how to use it, only to discover soon after that dput isn't the
main tool for uploads or dak commands anymore. Other newer and more
complete tools should be promoted instead. Perhaps it is also easier
to maintain and keep all tools up-to-date if we have fewer redundant
ones.

I think it is time to remove dput from Forky, and later from Debian altogether.

Thanks,

Control: severity -1 wishlist
report does not describe any violation of policy or unsuitability for use.
I am changing the severity accordingly.

Is there an open bug report for that specific feature request? I can't see
one reported on the ‘dput’ package. If this feature is wanted, please make
a detailed bug report specifying what should change in ‘dput’ to enable
that feature.

Absence of a desired feature does not warrant a request to remove this
package from Debian.

This paragraph seems to be the main motivation for this bug report.

I disagree. If there are features ‘dput’ needs, my preferred approach is to
add them to ‘dput’ and make the replacement unnecessary.
