Would it be wise to delete all cc_payment-gateway.php files that are not in use?

There is no reason to have them if not used, AND it is RARE for a store to change payment gateways -- and if so, then a restore of the appropriate gateway is quite simple. What do you think?

I think it is a good idea. But it is important to mention the following things:

* please delete only the unnecessary 'cc_*.php/ch_*.php/ps_*.php' files. If you delete some other files, for example 'payment_cc.php', your payment gateway will not work

* it is necessary to restore these files or alter the upgrade pack, if you decide to upgrade
