Sorry for late reply,

The conclusion was basically not use section flags to identify which
section should be stripped out or not, so, it requires other mechanisms
for explicitly specifying which sections should be removed, as eu-strip
does using arguments.

Worth it mention here, that my last test shows that .ctf section is not
stripped by ue-strip because it doesn't have a "debug" section name.
