config loading even if cond = False ... is that intentional (and if so, why)?

[HotwheelsSisyphus]

Hi,
I've been getting error messages (no package.preload["whatever"] etc.) for plugins in /opt and finally figured out why: Even though I set the cond key to false, and the plugin was not loaded, packer was still running the config function for that plugin which of course requires the plugin to be loaded.
E.g. in

use({"blabla/yaddayadda", 
cond = false, 
config = function() require'yaddayadda'.setup() end})

I wonder if that is intentional? I imagine that even in a lazy-loading situation it makes no sense to call the post-load function before the loading happens, but then again I'm still really new to all this so maybe there's a good reason...
Thanks!
