My biggest issue with TailwindCSS was the ugly way of using background images with it. I had to inline background-url property and it was not clean. And I know I was not alone, because other frontend developers said the same thing. It looked similar to this:
<section class="bg-accent-dark bg-cover"
style="background-image: url({{ 'images/home/hero.jpg' | asset_url }})">
Note: We use liquid to generate url to an image placed on CDN.
Couple days ago, when I was doing six different themes in TailwindCSS using six different configs (I will report my findings in another article) I discovered that it can be simplified. Because CSS file is also on CDN, and the background-image can be customized in TailwindCSS config (read more), it can be replaced with simple bg-hero after adding its definition into theme extend section:
backgroundImage: {
'hero': "url('../images/home/hero.jpg')"
}
Now, our hero element HTML looks like this:
<section class="bg-accent-dark bg-cover bg-hero">
And I think its much cleaner! Reading documentation paid off :)

Because with TailwindCSS (and especially when doing six different themes with one set of CSS files) I want to keep my CSS untouched as much as possible - having those definitions in config means those definitions will be generated per theme and included only the one needed for particular theme.
So two reasons: It's tailwind way and themes constrains make it easier to mantain later.
