Im wondering how y'all manage to replace all those built in WC scripts (and any plugins) with custom code tho?
Dev-Time wise seems a bit harsh.. The cart updating, the order generation from checkout, all the store notices, messages and most importantly form fields -> form submission seem to be heavily depend on those scripts.. Just wondering, any tips here r highly appreciated if there's some nice workflow or "shortcuts"

P.S: Still relevant today.
You could also do (functions.php)

add_filter('woocommerce_enqueue_styles', '__return_empty_array');

for CSS in 1 line pretty much.. it's in the Theming Docs.

Side Note:
This still seems to work for me with all latest versions of WP & WC...
Don't forget to add it inside a function, and then add_action to invoke it...

IF you are using latest version of Woo, you need to add these three lines to remove ALL styles

wp_dequeue_style( 'woocommerce-general' );
 wp_dequeue_style( 'woocommerce-layout' );
 wp_dequeue_style( 'woocommerce-smallscreen' );

function gist_rm_wc_scripts() {
   if (function_exists('is_woocommerce') {
     # wp_dequeue above here
   }
}
add_action('wp_enqueue_scripts', 'gist_rm_wc_scripts');

Hey guys, I have disable WooCommerce styles and scripts sitewide as I need good performance and it was killing my site performance. I have an issue now where the login form and other account forms have no styling. How can I target the account pages of members so that it displays the styling only for any user account related pages?

Wrote an article having comprehensive code for this.
