Ok this is hypothetical but still .....
It was the cause of much debate in the office today so interested on thoughts.
I have a 'professional' career. When I married I kept my maiden name for work, I took my DH's name for practical reasons for 'homelife' which became important reasons when we had DC as I wanted to share their name.
Subsequently I moved overseas and due to various issues with my passport and visa it was easier to work under my married name. I now consider DH's name to by my own.
The comment was made in relation to someone who had reverted to their maiden name that it would be weird to keep a DH's name if you separate and in fact it shows the world you are still emotionally attached
