On edit - now that I re-read your reply... why argue that they could get this done before 2028 when your own link says they're in the process of targeting the 2028 election cycle?
Article XIX
if the amendment or amendments as proposed or as amended shall be agreed to by a majority of the members elected to each of the two houses, such proposed amendment or amendments shall be entered on their journals, and the ayes and noes taken thereon, and referred to the next regular legislative session convening after the succeeding general election of members of the assembly, and shall be published for three months previous to the time of making such choice; and if in such legislative session, such proposed amendment or amendments shall be agreed to by a majority of all the members elected to each house, then it shall be the duty of the legislature to submit each proposed amendment or amendments to the people for approval in such manner and at such times as the legislature shall prescribe; and if the people shall approve and ratify such amendment or amendments by a majority of the electors voting thereon, such amendment or amendments shall become a part of the constitution on the first day of January next after such approval.
So on correction - The "general election" requirement isn't that the final vote can't be held before then... it's that the second legislative vote can't be held before an intervening general election of the state legislature.
Same effect... no change is possible in time for nex year's election
