This one uses lsattr, but guards the execution with checking if it
exists first, so no strict dependency needed for this. Basing my
assumption on the file name a Suggests would likely be more warranted
than a Recommends.

The postinst maintainerscript does indeed use both chattr and lsattr.
Both of them are guarded with the debconf variable
resolvconf/linkify-resolvconf having to be TRUE, which is the default.
A dependency is thus currently needed here!

An alternative approach if there's a reason to consider avoiding adding
a strict dependency would be to refactor the debian/config to check
for chattr/lsattr existance and if they're not available force the
debconf variable resolvconf/linkify-resolvconf to false (likely together
with a debconf prompt stating that). I'm not sure if the extra
complexity is worth it and it would be great if maintainer(s) could
comment on this.

My conclusion is that a e2fsprogs dependency is likely the best
solution.
