IFS Cloud24R2 - Report Designer: Déjà Vu fonts

Hi Report experts,

I can see following in the IFS Cloud 25R1 Deprecation Log.

Starting with IFS version 25R2, Monotype fonts (Arial, Arial Narrow, Courier, Garamond, Times New Roman) will no longer be included in IFS Report Designer and IFS Report Studio. To maintain consistency, Déjà Vu fonts will be used as the standard .

My question is, what is the impact on custom Report Designer reports ( custom Report Designer reports built from scratch for customers prior to 25R2) in case customer will not have all these Monotype fonts after upgrading to 25R2?

Is it just a matter of adding an entry to Report Fonts/Font Substitution OR
Any manual Report Designer layout adjustments required for each custom Report Designer report?
