How to make BEM and WP friends?

Question

css

Good evening! I work in a team, a teammate who writes on WP complains that when everything is hung up on classes, it's bad:

<section class="sec1">
 <h1 class="title title_black">
 <p class="text text_with_some_css_style">
</section>

Says it needs to be like this:

<section class="awesomeClass">
 <h1>
<p>
</section>

.awesomeClass h1
.awesomeClass p

This is an oversimplified version, because having more than 40-50 pages in the project, everything results in............ Offers to tie everything to 1 class and foresee possible variations in advance: i.e. if in the second case UL is also inserted into the section, then it must be styled in advance in css: What if paragraphs or the same lists differ inside the section ?? Do like this:
.awesomeClass ul

.someClass1 ul:first-child
.someClass1 ul:nth-child(2)

?????????????????????????????????

Well, in general, almost all things in WP, widgets, menus, etc., you can change the template for all of them and there will be no problems.
