Rush did the same: viewing it as equal contribution to the band being the band - beyond just writing and arranging.
All the give and take in bands that the members' bring: 'this part's rubbish, try this,' 'How's this for an album cover idea?' etc.
It makes sense unless you are literally the one who does everything. It avoids complicated arguments and legal wranglings later: The Smiths, Pink Floyd, etc. etc.
