I definitely agree with this - the point of Marxism is that your exact policies should depend on your material conditions. The Bolshevik Party is a good example of this. At some points, they advanced workplace democracy; at others, they returned Bourgeois managers to the factories. At times they supported individually owned farms, and at others forcibly collectivized ones, and at still others allowed for privately owned plantations. Lenin called for the party to participate in Bourgeois elections, but the vast majority of Bolsheviks took the ultra-left position and boycotted them. Sometimes decentralization is preferable - but centralization is often necessary! These are all dialectics that cannot be resolved dogmatically.
