It depends on the use case, but generally speaking, yeah.
It's less secure than a dedicated device for storage of the 2FA secrets and code generation, sure, but I don't see how it's any less secure than using a service like Duo to manage and sync your secrets.
Furthermore, I'd argue it's substantially more secure than the recovery process for almost all of the services I use, most of which offer an option to reset by SMS.
Finally, keeping your 2FA secrets in your password manager is very likely not to change the attack surface for most people anyhow, as most people keep their recovery codes in their password managers as well.
