PHP7 and Debian: does not support version 3.0.3 of the memcached extension

[COil]

Hello, on Debian 8 I have installed memcached with:

apt-get install php7.0-memcached

I've got the following this error message:

LswMemcacheBundle does not support version 3.0.3 of the memcached extension

That version is too "new", any chance it could be considered as 2.2 and work ? I see the if / else in the MemcacheInterface file regarding the version it get.
