I use Chromium the same way, to see if websites are broken also there. But often also to see how websites behave while developing, because most people use a chromium based browser, so if it looks correct there it should "be fine".

I just found a bug in my code, where I generated dates using unix timestamps. If the unix time stamp is bigger than 2^31 - 1, or January 19 2038, it will overflow and restart at 0.

Also the numbers show that it is totally worth it. The website has no tracking, but I can see the growth in the Google Search Console. Impressive!
