Thanks for reaching out in relation to this @Chris. Just one small (but important) point here - these are warning messages rather than error messages.
They are simply letting you know that there are things that can be improved, or things that will change in the future. They will not prevent you from publishing.
Nope, absolutely not and really disappointing that you would even think this.
Yes - we’re replacing it with a the updated component in the future. This has been discussed several times in the community already.
Agreed, it’s a “weird” one - but again, it’s a warning rather than an error, (associated with one of our other components if I remember correctly? ) and will not in any way prevent you from publishing.
Since you said it twice, I’ll reiterate - no, this will not affect your ability to publish.
