Accepted Answer

No, there is no longer any danger here. The decos were not affected either: https://www.heise.de/news/Sicherheitsupdates-Unbefugte-Zugriffe-auf-TP-Link-Router-moeglich-9297306.html and the list of affected devices: https://jvn.jp/en/vu/JVNVU99392903/
Decos are not listed.

Answer

For my use it works very well, music, TV, video calls, etc.
My PCs have extra protection, and apart from being connected to the network only temporarily, I don't keep sensitive data.
