Hello,
1/ No you don’t need to take care of these changes. We copied templates/breadcrumbs.php to your child theme and removed one line to make it work for you as you wanted to.
2/ We enabled you Move Product Name in Breadcrumbs option -> https://prnt.sc/IR2fBp1NPBCv and rewrote woocommerce/single-product/title.php in your child-theme with next changes -> https://prnt.sc/BMIVUep2DDpx
3/ Fixed globally in our css
4/ We added next code add_filter('etheme_breadcrumbs_shop_step', '__return_false');
to your child-theme/functions.php
Regards
