LcSuggest

Hello
Congratulations for the new upgrade. Yesterday upgrade my version 2.0.2 to 2.0.3 .
I use these link http://omeka.org/codex/Upgrading
and now I see these plugin. Lcsuggest.
omeka said that
LcSuggest is not plugin valid.

My question is if I can delete of my list of plugins in my site ?

thanks
