Hyphenated names are so 90s corporate cliche, and not to mention rooted in the elitst and aritocratic traditions of patriarchal 19th century Yuropean nobility.
Hyphenated names were invented so a lower ranked social status man could attach his name to the lineage of the higher ranking noble's daughter he was marrying. This way the lower ranked man could still assume the higher prestige and privlieges of the spouses lineage while still maintaining his dominating and oppresive gender role within the traditional marriage hierarchy.
The truly egalitarian 21st century option is for the couple to adopt a whole new name. Like Taylor Dautomer or Taylor Domer.
