Yes, some shops intentionally want to slow down the software dev lifecycle if the software is particularly critical. A lot of aerospace shops do this. Classical example is medium to large satellites: they cost anywhere from $100M to $1B, they only launch once, they pretty much need to work correctly the first time or you might lose the whole thing. Two line code change? They don't care, review board is going to spend an hour picking it apart. The same applies more broadly to other controlled/regulated software, software that is safety critical, and software doing core banking/financial stuff.
