My answer is "Yes".
The rifles I like to hunt with the most just happen to be .308s, but I kinda feel deprived without a good-shooting .30-06 in the safe.
I obtained a LA receiver a couple of years ago and built it into a .30-06.
For no particular reason. It's been in the field twice in two seasons, I may not hunt with it for a couple more, but it's there if I want to.
I can live with just having either one, having both is mo' better.
