Because of bug 1711700, we cannot enable the branch with just an empty object (attempting to use the normal non-experiment screens) and will need to specify screens in the JSON. We can workaround by providing a screens array which will dynamically switch a "default" button to "primary" button for users who can and need to pin:

https://searchfox.org/mozilla-central/rev/443f87caa5fadba920b0382e12874693d6c6133a/browser/components/newtab/aboutwelcome/lib/AboutWelcomeDefaults.jsm#586-602

However, the string that gets used has slightly different casing than what is currently shown in 88:

mr1-onboarding-set-default-pin-primary-button-label =
  Make { -brand-short-name } my primary browser
    .title = Sets { -brand-short-name } as default browser and pins to taskbar

onboarding-multistage-pin-default-primary-button-label = Make { -brand-short-name } My Primary Browser

There are also other changes that happen when Firefox can be pinned for the holdback group, e.g., different text, default gif when waiting for default:
https://searchfox.org/mozilla-central/rev/443f87caa5fadba920b0382e12874693d6c6133a/browser/components/newtab/aboutwelcome/lib/AboutWelcomeDefaults.jsm#445-489

So we can switch the targeting to be windows 10 1903+ and assume firefox will need to be pinned. Or keep the current targeting of first startup en users and always show "default" even if firefox needs to be pinned?

With bug 1711700 wontfix for 89, we'll need to either:

• target recent win 10 and show the "primary browser" welcome
• show "default browser" targeting general firststartup (windows)
