_wfls_role_counts and MEMORY table type

I’ve used the plugin for a couple of sites now and I appreciate the optimizations it is making. However, I’m curious that when using the WordFence plugin, it is detecting a table of _wfls_role_counts that is using the MEMORY type and offers to convert it to InnoDB. Apparently the MEMORY type should be faster than InnoDB. Here is a link detailing this information:

My guess is that it would be beneficial for the plugin to not identify MEMORY table types as candidates for conversion to InnoDB. Could that be added to the next update? Thanks!
