I really want to use aspect-ratio, but a recent thread on HN, that now I can't find, has me worried that I shouldn't be counting on CSS until its been supported by the browsers for a couple years.
The recent thread was about all the reasons that even "evergreen" browsers might still have plenty of people using old versions, and was on a thread about a Chromebox still in use that could not have it's version of Chrome updated.
You should generally make these decisions based on the usage stats of your own visitors. Caniuse.com for example lets you import Google Analytics data.
That makes sense, but I'm still cautious of just automatically doing it.
1) it can be a bit circular; if the site doesn't work with a browser, people on that browser are probably not going to spend much time there
2) Depending on what you are doing and your goals/mission (I generally work in academic/non-profit/public sector), you may have a mission that encourages you to be accessible to people on "old technology" regardless of the % of visitors.
I've been thinking maybe a standard of 1-2 year old version of popular "evergreen" browsers might make more sense, than what many people default to "latest version".
Which would put aspect-ratio not quite over the finish line, alas.
