No.
A wallet should *never* create
Good morning DING FENG,
While your concern is valid, the general intent is the below:
1. We will use a scary name like SIGHASH_NOINPUT_UNSAFE to explicitly inform
to wallet and Bitcoin software developers that the flag is potentially unsafe.
2. SIGHASH_NOINPUT_UNSAFE is intended to be used
Hi,
I'm a junior developer and a bitcoin user.
And I have read this thread carefully.
I'm very worried about "SIGHASH_NOINPUT".
Because "SIGHASH_NOINPUT" looks will be widely used, and it makes reuse
address more dangerous.
Now, most donate addresses (even bitcointalk.org and bitcoin.org) used

A convention in Haskell libraries is to use an "unsafe" prefix to any function
that may have side effects (here be dragons, etc)
I'm happy with a _VULNERABLE or _UNSAFE postfix as a standard way to signal
this.

Something like this might also be useful for several use cases related to
RBF. For example:
Alice sends Bob an RBF-activated transaction T1 with the intention of
bumping its fee if necessary. Bob wants to send these funds to Carol, but
cannot wait until T1 confirms, so he crafts a transaction T2
