Here's a very compact solution.

Template filter:

@register.filter('placeholder_is_empty')
def placeholder_is_empty(request, slot):
    page = request.current_page
    placeholder = page.placeholders.get(slot=slot)
    return placeholder.cmsplugin_set.exists()

Usage in template:

{% if request|placeholder_is_empty:'myplaceholder' %}
    
Here comes some content... 
{% endif %}
