Basically this.
7.62 NATO is "better" by virtue of being at least slightly more contemporary than stuff like 7.92 Mauser and .30-06, but you're still generally going to have some sort of legacy cartridge in one form or another and you're not going to suffer immensely by retaining it because full calibers are no longer The Thing™️. As long as you do have access to some sort of intermediate cartridge for general use, it doesn't really matter if your sniper rifles are in 8mm or .30-06.
