Not really, the very idea of conservatism is based around not doing new things. Without passing judgement on whether or not that's a good policy standpoint, it's clear the parties are asymmetrical - one wants to pass new policies to change something , the other oppose that.
The GOP policy website this election was literally copy pasted from 2016 - it infamously contained references to how they need to change things the incumbent president did.
That's not quite true. They just renewed the 2016 platform. Their resolution states "without adopting a new platform" and then attaches the full 2016 one below it.
in Obama's memoir, he recalls he and Biden trying to explain the policy merits of a bill to Mitch McConnell, who responds "You must be under the mistaken impression that I care”
It is actually true that in 2020 the RNC didn't even bother to adopt a new platform [1] but instead pledged fealty to Donald Trump and explicitly, in their own words, "reject the policy positions of the Obama-Biden Administration,as well as those espoused by the Democratic National Committee today".
In their own words they define themselves by their opposition to democrats.
