The ISW website has an excellent article on the effects of US restrictions on the use of donated weapons against targets in Russia on Ukraine's ability to defend itself:
Current US policy prohibiting Ukraine from using US-provided weapons in the territory of the Russian Federation is severely compromising Ukraine's ability to defend itself against the renewed cross-border invasion Russia has recently launched in Kharkiv

The war may seem "quiet" due to the lack of large areas of territory changing hands, but the Russian offensive is still continuing in a serious way and the ability of Russian forces to have a sanctuary across the border from Kharkiv enables that. It also draws Ukrainian forces away from other areas of the front where Russia can try to use their manpower advantage to attrit Ukrainian units.
To get a sense of how much fighting is going along the entire 600-mile front just look at the list of locations where the Russians have been attacking over just the last 24-hours from
ISW's Daily Update:

I don't see how anyone can take from this that Russia will be content with just holding on to what they've captured so far. They continue to attack all along the front - despite heavy losses in personnel and equipment and obviously believe that they can ultimately win a war of attrition against Ukraine in terms of manpower and in terms of their industry's ability (along with Chinese, North Korean and Iranian support) to ultimately outpace the West's ability to supply Ukraine.
We need to let Ukraine take the gloves off and use every tool at their disposal to defeat the Russians. And the West needs to really put our military industry into high gear to pump out enough weapons to let Ukraine do the job. Ukraine needs that serious firepower advantage to win because frankly unless we put NATO boots on the ground (which would take this war to a whole new level that I don't think anyone wants to see), Russia has the potential to bleed Ukraine dry of manpower to the point that they will be unable to generate enough forces to conduct any significant offensive operations.
