Like all shells, PowerShell is split between being a scripting language and an interactive shell.
PowerShell leans a bit more towards being a scripting language than an interactive shell, so things are more verbose, as befits a shell script that needs to be read and updated later by a different programmer.
But yeah, lots of little trade offs like that permeate the language.
Less work than trying to add named stacks to bash. If it's so central to your workflow that you're willing to put up with the rest of bash just for it, adding a couple lines to your profile can't be that big of a deal.
