Is there any harm/risk if we create a new term using New-PnPTerm and supply an on-prem GUID

Currently we have one sharepoint online tenant and another sharepoint on-premises farm. where we have migrated some of the on-premises sites to sharepoint online, and other sites which need re-development are still inside the SP on-premises. and as part of the migration, i have migrated all our term sets and their terms, where the migration tool created the terms with the same on-premises GUIDs/Names. but today i want to add additional term and our migration tool license has expired, and i am not planning at this stage to get a newer license to just migrate a single term. so i did the following:-

1. inside the on-premises term set i added  the new term as usual.

2. and then i am planning to migrate the on-premises term to SP online using this command:-

New-PnPTerm -TermSet "Departments" -TermGroup "Corporate" -Name "Finance" -Id 34da8b3b-******-9f5e-0863041f1ef6

 where the 34da8b3b-a3cb-******-0863041f1ef6 is the term's on-premise GUID.. so my question is if creating the online term using the above appraoch is valid? i do think it is valid,, because when we migrated our on-premises terms , the migrated term got the same GUID as the on-premises ones..
