Comment 4 for bug 2015867

This isn't about the deb size, but about the size as extracted on the system.
Especially headers will most likely compress really well into the deb.

Comparing the latest 5.19 with the recent 6.2 [1][2] that got through propose migration we can see the increase just fine. debsizes as downloaded and sizes as extracted on disk (just dpkg -x, you do not need a system to install):
[I'm sure LP display will break this, looks reasonable in monospace) - [5] is a public gspread of the same content.

Further [3][4] show that this isn't specific to the -kvm kernel. It is in the generic kernel as well. New code might have more modules, so while it is quite a lot and we need to ask ourself if anything could be done it might be a necessary step. But the sources, they have grown so much and are default installed. The bump to default image size is quite much IMHO - enough to discuss about it here at least.
