This doesn't really seem specific to Workstation.  We should aim for
distro-wide first, so other products have a similar look and feel.  If
they need to deviate, they can do so later.

I do have other product specific things here.
This policy is written with two facts in mind:
1) Fedora's default desktop offering is Fedora Workstation.
2) Fedora Workstation uses GNOME by default.

As such, if the WG would decide to switch desktops, this policy will need to be re-evaluated.
Furthermore, this policy does not aim to apply to all applications in the distribution. It's meant to apply to anything we include by default in our default desktop product.
If other applications want to follow it it'd be great, because it will improve user experience, but I can't force them to.

I don't understand the "default launcher" follow on, nor why it isn't
it's own bullet.

It's a typo.
The same icon must not be used for more than one application launcher that is installed by default.
We can't enforce non-default apps to have unique icons. This is there because it's clarifying on the word unique.

This last bullet seems product specific.  That might be an addendum
per-product, since the "core applications" are going to likely vary.

Same comment as I said before. If other products or spins want to base on this policy, they can copy it and make the changes they need.

Uh, I kind of object to this bullet.  This is a Fedora policy/product,
not a GNOME one.  If Fedora sees a non-GNOME application as part of
the core desktop experience, it shouldn't have to justify it based on
what upstream GNOME thinks.

If we install it by default and GNOME thinks it's core then having it removable would hurt our user experience. We can't have users removing Software itself, for example.

That seems difficult to enforce/police.  What happens if an app meets
everything else but then fails to do this?  Do we then yank it out?
Who's going to sit there with a stopwatch and time every app?  I
realize this is a should, but it seems unnecessary.

It's a "should" item. It will make UX better. It's not something you can enforce, and therefor it's not in the must column.
It's included because it's something many people don't pay much attention to, and if an app takes a long time to start (that is, show any UI, in case of libreoffice or similar big apps, a splash screen is fine) we should consider removing it from the default set or at least prioritize fixing it.
