To have string stored as UTF-8 only, no conversion required for 99% of our
use.

ICU has limitations in the utf-8 mode. To bundle UTF-8 or ask custom build
could be a problem as well. The other point to check is whether ICU can
have two installs on the sane systems, one with the flag and one without.
It could help as distros can then provide both.

Maybe I was not clear here. What I am not looking for is to delay a
possible 6 release to 2-3 years later. Ideas, like yours here, are indeed
more than welcome.
