At the end of the Castle Keeper's Guide there are optional rules for introducing "Advantages" in C&C which are essentially feats. It is suggested that they are giving uniformly to all classes or instead of class abilities (and hence given at different frequencies depending on the class).
Examples are given for a range of advantages equating to feats for race, combat, magic, etc.
If you are interested in this I'd definitely recommend picking up the CKG which is full of great option material (to give a sense of the book it is the nearest one I've read in terms of flavour to 1E DMG).
Including the . . . poetic . . . prose contained within it.

But a lot of very good ideas!
