Opponents are cheering the unceremonious demise of Boston's bid for the 2024 Summer Olympics, but some proponents are wistfully wondering what might have been.

Supporters are worried the sometimes rancorous debate that consumed public interest since the city's surprise nomination in January will leave lasting scars.

Others are concerned the consensus around finally fixing some of Boston's most intractable problems, from a creaky transit system to a lack of affordable housing, will evaporate.

For some, there's a sense that the bid's demise only furthers Boston's image as a city of cynics and curmudgeons with a "can't do" spirit.

The U.S. Olympic Committee officially severed ties with Boston on Monday, saying it was exploring other options for the international competition after picking it over Los Angeles, San Francisco and Washington, D.C.
