Well, disabling the SMBv1 feature will also make any of shared folders, mapped drives won't work at all. all the shared drives will get disconnected & unreachable.
It depends on how's ur requirement & usage. Just take a precaution here especially if u r in the organization or company environmental, it might be needed so by disabling it, u will unable to reach the file on the network.

beware of v3 variant!
