It depends upon the field you are talking about for diminished return and less innovations. Returns have been thoroughly diminished when it comes to raw power in weaponry for instance. With anti-ship missiles already it is rather 'you get hit and you die'. Railguns haven't really been working out well for instance, and even if they did succeed all they would do is create 'stable magazines' while adding 'unstable' additional power production. Precision is the area where real work is being done, lumping in drones as an example of precision compared to say missiles or bombs which just explode at a destination, or mines which just explode when anything triggers it.
There are some major advancements in biotech for instance that are nothing to sneeze at, and even more in the pipeline (which admittedly may not pan out). Organs may not qualify as an invention technically, but being able to manufacture them certainly does. Not to mention how environmental tech is needed now more than ever.
Science being less convertible to inventions could have counterintuitive effects if it were true. Like smaller nations being in a 'don't even bother' situation while superpowers gain a literal monopoly on invention due to the rareness raising the barrier to entry to get anything meaningful out of it.
Politicians defunding and discouraging science is based more around memes and suppressing dissent than anything concrete. The reason not to create such 'stability' is generally that when the rest of the world passes by it will not be kind to you. But even if science somehow became literally useless tomorrow (an impossibility, of course), I highly doubt that politicians would not be such rigorous cost-oriented stewards that they would consider it worth the political capital to uproot the entrenched bureaucracies which no longer serve a purpose. Even if they knew it for certain was useless they might consider the spending a worthy price to pay for false hope. Crowds get real ugly when you tell them that things will never get better.
