• margin-block
• margin-inline
• padding-block
• padding-inline
• border-block
• border-inline

These logical properties are useful features. However, when used in combination with CSS written in traditional physical properties, it results in a mix of logical and physical properties, compromising code consistency.

If there were properties named in physical versions (such as margin-vertical, margin-horizontal, padding-vertical, padding-horizontal, border-vertical, border-horizontal), they could be more conveniently used in physically-based CSS.
