The abuse of the user agent for tracking and unreasonably blocking browsers - Chrome only websites that work fine when you spoof the user agent - out weighs the usefulness of being able to work around browser specific bugs.
These days old browser versions are for most companies, a problem of the past. IE is well and truly dead, and almost all users have auto updating browsers now.
Websites shouldn't really attempt to fit themselves to the browser, just detect which features are available and if there is some odd browser bug, wait until it's patched if it's affecting a major browser.
