“Grant Establish and Ordaine that for ever hereafter there shall be a liberty of Conscience allowed in the Worshipp of God to all Christians (Except Papists)”
Do you think they disallowed “papists” because, historically speaking, Catholic countries have not allowed other Christian groups the same liberty of conscious in worship?

Not, not at all.
1) Catholicism was THE only Christianity Western Europe had ever known really. To say that there is parity in granting Catholics the right to worship in a formerly Catholic country (violently forced into Protestantism by fear of the Tower and headsman) with granting Protestants the right to worship in a still Catholic country is a denial of historical reality (not to mention common sense) concerning the origins and history of both faiths.
2) Protestants were forced to agree to freedom of worship for all Protestants simply because no Protestant sect - and they are all sects - could claim to be anymore authoritative or right than any other. Protestantism leads to indifferentism in other words, so why not allow freedom of worship for all indifferentists?
3) All English Protestants were united in hatred and fear of the Catholic faith. After all Anglicans worshiped in buildings stolen from Catholics; Protestants in general failed in debates and disputes against Catholics; English culture, socially retarded by the violence against and destruction of art and cultural development of the English Protestant revolutions, was deliberately manipulated by the English Protestant divines, English Protestant popular culture, and the English Protestant government to become zenophobic against things smacking of Catholicism or otherwise continental. Ralph Adams Cram, one of the greatest 20th century American experts on art and architecture, and a Protestant, wrote and spoke about this extensively.
