I decided to elevate my comment to an answer.
When this is all over, and most of your readers will probably know multiple people who died during the crisis, this would not be a good [look].
This is a global crisis that is only just beginning. By the time the dust settles, millions may have died from the virus alone. It would be a rare reader who does not personally know someone affected. More will have died because of how overwhelmed the global healthcare system is.
Even more will be affected by the economic fallout.
Viral infections can have lifelong consequences, even if you live.
If you're in a medical field, many of your readers will be caregivers who were worked to the bone for months, and had to make impossible triage decisions.
For your readers, researchers are forced to halt research, often at great expense. Many studies cannot be paused for three months and picked up at the same place.
And you're proposing to put in your acknowledgements "gee I got so much done while quarantined!" This is offensive at best, and obscene at worst. We in universities are extremely lucky that our pay will most likely not be stopped, and we can just pick up and work from home. That is not happening for most of the nation.
Frankly, I would be ashamed to be your co-author, and if you were in my field, put you on blast across every channel I knew how. Do not do this.
