it really a problem? It seems to me that successful projects are often linked to one person, even when there are obviously a lot of others making significant contributions (like in the MyHDL project, thank you all!) Somehow it seems to give projects an identity.

When turning an LED off, set the I/O pin as input with pull-up. The protection circuitry added to the button will make the LED shine brighter when the
