If nothing else Abseil gives you state-of-the-art hashmaps that run circles around the STL ones, which are slow pretty much by definition. The spec precludes the modern ways of implementing them.
Sure; you can roll your own, or you can use one of the many other libraries that provide alternatives. There are obvious downsides to the former, and the latter is basically equivalent to using the Abseil ones in terms of practical tradeoffs.
Chromium uses hundreds of other open source libraries. Is there something about Abseil specifically that sticks in your craw?
