Should we add the 'apt list --upgradable' output to update?

[eddelbuettel]

Running wajig update already fills a screenfull or two when there are more repos registered (as I do here for chrome, zoom, code, rstudio-via-a-local-PPA, syncthing, and more) so adding what would be updated might be nice. Now I just did

[.... earlier invocation of `wajig update` and its initial output omitted ...]
4 packages can be upgraded. Run 'apt list --upgradable' to see them.
This is 13 up on the previous count with 13 new packages.
There are 0 new upgrades                     
edd@rob:~$ apt list --upgradable

grub2-common/oracular-updates 2.12-5ubuntu5.3 amd64 [upgradable from: 2.12-5ubuntu5.1]
edd@rob:~$

Might be nice to see those four lines at the end of the initial call. Thoughts?
