Sure, *if* someone is willing to maintain. But, as a maintainer of a
number of Python packages, I want to get rid of Python 2 support ASAP:

* Many upstreams already drop Python 2 support from their newest
  releases. Keeping Python 2 would either mean to stay with the older
  version completely, or to split the source package into a Python 2
  and a Python 3 version. Both is ugly.

* Many sources, especially when they provide Python packages only as a
  secondary goal, are not supporting to build Python 2 and Python 3 at
  the same time. Aside from non-pythonic build systems (cmake for
  example), there are f.e. complications with tools built on top of the
  Python package.

* The EOL of Python 2 was announced long ago, but many people didn't
  switch just because it is still there and supported (experience from
  my surrounding). Keeping Python 2 supported only shifts the problem
  for them by another two years

So, while I would not *encourage* people to drop Python 2 support in
their packages, it is perfectly OK if a maintainer does so. If someone
else wants to jump in, he still can upload his own legacy Python 2
source package. And I will (recursively) remove Python 2 support from
the packages I maintain whenever I feel that support becomes difficult,
for any of the reasons stated above (with astropy as temporary
exception, due to the importance of the package).

Best regards
