My grandfather drove a truck for the Finnish Army in WWII and helped drive them out of the country.
If I was Finland, I would continue as if Russia had changed nothing at that camp, however reassuring the changes there might appear to be.
Even if it's "only" a training camp now and not a fully operational military installation, I'd still not let my guard down just in case the Russians decide to take a "special training exercise" over the Finnish border. That is the sort of thing they like to do, after all.
Finland hasn't let its guard down since WWII. Russia is a very familiar beast.

They can fucking try, but our border is a bit more geographically challenging than the ones Russia has been forcefully shifting for decades in Ukraine.
