I question how accurate "slightly" is.

My understanding is that soft reconfiguration inbound (whatever the 
syntax for a given IOS is) causes a full copy of the received prefix 
list to be retained in memory for each of the peers with soft 
reconfiguration enabled.

So, to me, the amount of impact to memory will be based on both the 
number of prefixes advertised and the number of peers that soft 
reconfiguration is enabled on.

Please enlighten me if I'm wrong / misunderstanding something.
