Found it, but all they do is to run tabbar-local-mode, which overrides  
`header-line-format' after ERC has been entered, so that's really just  
a workaround.

What ERC could do is to only set `header-line-format' if it isn't  
already set in the buffer (by another package).  This, however, might  
not be the right solution in all cases.

I wouldn't invest much time into this - the "right thing" would be to  
implement tabbars at the C level.
