uniform image size for product images!

I cannot understand why there is still no solution for one of the most important functions, namely that all product images have a uniform size. With a CSS instruction, this can be implemented in 5 minutes. In this context, it would be desirable if there were a basic function so that fundamentally all images are the same size, e.g.:

<style>
table img{
height:100px!important;
max-height:100px!important;
width:auto!important;
}
a img{
height:180px!important;
max-height:180px!important;
width:auto!important;
}
</style>

My recommendation for a future feature would then be more comprehensive:

Basic: all images the same size
Advanced: enlarge/reduce individual images (and not, as currently, all at once!)

Advanced: change the size of all images uniformly, e.g., maximum width, etc.
