I don't believe things will go that far, and the reason they were shut down is that they enhance privacy for BTC users, and we all know the government is targeting any service that enhances privacy, by charging them for allowing money launderers conceal their tx's. So Electrum and some of the services you mentioned do not fall under this category, because they do not enhance privacy or make it hard to track BTC tx's.
Electrum comes with coin control, lightning network, Tor, plugin support, custom Electrum server support-- all of which
allow privacy enhancement. If you pass a legislation that treats Samourai Wallet as illicit based on the criterion that it enhances privacy, then you open the Pandora's box to ban everything that can help you enhance you privacy.
Everything, even your Internet connection; it's
that vague.
