To the extent that startups are swinging for the fences, everyone should be well aligned (0.5% isn't much unless the total is pretty huge), since you're trying to optimise for the extreme outcome, rather than "average", having such a clause could let you benefit in other dimensions that help you towards your goal.
I'm speaking in generalities since I'm not sure about specifics, but as an example an investor might be willing to accept a smaller (i.e. less controlling) stake with liquidation preferences for the same price, which leaves you more equity to sell to others.
