I consider it as basic security measure as SSL. Otherwise any MitM can easily redirect users to a phishing resource.
Did DNSSEC for company website, worked with zero maintenance for several years. On a cloud-provided DNS. Would want the same on self-hosted DNS too.
"Otherwise any MitM can easily redirect users to a phishing resource."
Yes, but with nowadays https/tls usage it's almost irrelevant for normal websites.
If bad actors can create valid tls certs they can solve the dnssec problem.
