This is a large reason why I was really annoyed when Google removed the "Merge Tabs and Apps" option back around 2016. With that feature, a bookmark to a URL could open up a new tab, appear in the list of active applications, and be closed just through that list. Effectively, there was no difference in usability between a bookmarked URL and an app that loaded the webpage in a captive browser, but you got all the sand…
Just as a different perspective I hated that feature. I use my list of tabs almost as a set of bookmarks and todos. Trying to find them in the recents app switcher sucked. I don't object to the feature existing of course just offering a perspective on why it maybe wasn't universally loved.
I suppose it was extra frustrating due to the slow removal of the feature. First, make it no longer be the default setting. Then, move the setting into chrome://flags. Then, periodically break the flag for it, depending on undocumented interactions with other flags, which A/B testing group you're in, locale, and phase of the moon. Finally, remove it altogether by arguing that nobody uses it. It felt like somebody had decided to kill the feature, and only later constructed a reason to kill it.
